Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4980, here are decompositions:

7 + 4973 = 4980
11 + 4969 = 4980
13 + 4967 = 4980
23 + 4957 = 4980
29 + 4951 = 4980
37 + 4943 = 4980
43 + 4937 = 4980
47 + 4933 = 4980

Showing the first eight; more decompositions exist.
